Welcome from Southern California! You've come to the right place for all sorts of info and pro advice. I've had chickens for just over one year and can say that no matter what the books and websites say, each chicken definitely has her/his own personality. I have six different breeds amongst thirteen hens, and they all get along just fine. They establish their pecking order and that's that, at least that's what I've experienced. Definitely do search this site and you'll get tons of good info. Best of luck and have fun!
